Overview
PP random copolymer is a copolymer resulting from the random distribution of ethylene in propylene chain segment. The resin has good transparence, glossiness, heat resistance and processability.
Application
PP random copolymer is widely used in the production of medical appliances with high transparence, such as medical syringes, medical infusion bottles, medical centrifuge tubes and sample tubes. It is used in the production of food containers, stationery, packaging materials and houseware.
Package, Storage & Transportation
The resin is packaged in internally film-coated polypropylene woven bags or FFS film bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
